Hello, on Monday I have an appointment at the mechanic to change all the fluids in my car because it already has 40,000 miles and I only periodically change the engine oil.
the mechanic has budgeted these for me.
Brake fluid: Motul dot 5.1
Manual transmission fluid: Motul Gear 300 75w90
Rear differential fluid: Motul gear competition 75w140
Antifreeze: Motul Inugel Optimal

It is all Motul because my mechanic works only with that brand. In Spain it is difficult to find American brands...

On Monday I maintain these liquids and look for recommendations.
